Surviving Sepsis bundle timer + lactate clearance
Measures the Surviving Sepsis Campaign bundle elements against the recognition time T0.

Example
- Sepsis recognition time T0
- 2026-05-19T12:00
- Initial lactate value
- 4
- Initial lactate drawn at
- 2026-05-19T12:30
- Blood cultures drawn at
- 2026-05-19T12:30
- Broad-spectrum antibiotic at
- 2026-05-19T12:45
- 30 mL/kg crystalloid started at
- 2026-05-19T12:45
Result: All hour-1 elements on-time per SSC 2021; repeat lactate pending at 6 h.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Hour-1 elements
- Lactate, cultures, antibiotics, fluids within 60 min of T0.
- Repeat lactate
- Within 6 h if initial lactate >=2 (Nguyen 2004 clearance).
What you enter
The sepsis recognition time, then the times for cultures, antibiotics, fluids, and vasopressors, plus the initial and repeat lactate values and when they were drawn.
What this is
Enter T0 and the timestamps for blood cultures, broad-spectrum antibiotics, the 30 mL/kg crystalloid start, and the initial and repeat lactates, and it returns each element's elapsed time, whether it landed inside its window, and lactate clearance.
When to use it
Use it during and after a sepsis presentation to see which bundle elements are still outstanding and to document the timeline. It reports timing against the published windows; it does not decide that a patient has sepsis, and it never orders a bundle element.
